Hi there Jas and we're glad you found us too! Welcome!
Yes, it is just fine to use the cable that came with your camera to transfer files to your computer. Only downside (if there is one) is that you are using your camera's battery power to do so. If your battery dies before you get all files transferred, that could be a problem. If, on the other hand, you have a power adapter for that camera so that you can run it off electric, then no problemoe!

If you wish to use a card reader, your local shop can show you which ones are compatible with your media type (compact flash, X-D picture, smart media, memory stick, etc.). You can find ones with and without cables; your choice. When I travel, I carry along a Zio! Microtech compact flash card reader. It's cableless.
Cheers!
